Necronomicon This evil spellbook replaces the BFG9000 in slot 7. The player can carry up to 150 fuel cells at once, or 300 if the backpack has been acquired. The flamethrower's ammo can be found in the form of fuel and fuel canisters, which replace the energy cell and energy cell pack respectively. It has a high rate of fire and damage, but as expected for a flamethrower, the fire projectiles have a limited range. Custom weapons Flamethrower The flamethrower replaces the plasma gun in slot 6. Rocket launcher The rocket launcher now fires a bright orange projectile, however this is only a cosmetic change. The ammo capacity has also been increased, from 200 bullets to 300 (600 with the backpack).
Modifications to original weapons Pistol and chaingun These weapons have had their rate of fire increased. It also has had its health greatly reduced to just 120 hit points. Instead of summoning lost souls, it now attacks directly with a pair of mancubus fireballs. Pain elemental The pain elemental appears with a greenish tint. Mancubus The mancubus has a completely new set of sprites, but the changes are only cosmetic. Imp The imp is now bright red and attacks with the more powerful projectile of the Hell knight/ baron of Hell, though in this case the damage range is 7-56. Content Modifications to original monsters Zombieman The zombieman is missing its head, however the change is only cosmetic and the monster remains identical in every other respect.
